When Halo 4 introduced Specializations in its multiplayer mode — a kind of Spartan mini-class that allows players to customize and prolong their multiplayer experience — only two of the Specializations (Operator and Wetwork) were made available at launch, while those who bought the Limited Edition of the game received all eight Specializations immediately. Over the weekend, those who began playing the multiplayer mode of Halo 4 before Nov. 20 received codes unlocking all eight specializations, Kotaku reports.
According to Kotaku, players who played Halo 4's multiplayer before Nov. 20 received emails with download codes for the "Specialization Priority Alpha", a DLC package that unlocks the modes.
At the moment, those who didn't purchase the Limited Edition of Halo 4 or receive download codes can still access the Wetworks and Operator Specializations after they reach level 50, although the remaining Specializations are yet to be rolled out.
We have contacted Microsoft to find out if the codes are being sent to everyone who played Halo 4's multiplayer before Nov. 20 or if there are territorial restrictions.
Update: A Microsoft spokesperson has confirmed that anyone who played Halo 4 multiplayer on or before Nov. 20 who also has an Xbox Live account in United States, Canada, Chile, Mexico, Colombia, Brazil, Japan, Hong Kong, Singapore, Korea, Taiwan, Australia, New Zealand or India will receive a Specialization code via email.
